are preferably used in the proportions state l Parts by Weight. Glue 36 Water 3d Acetic acid 9 W Wood alcohol e 'l0 Garbon tetrachlorid l- Benzol 12 In addition to the ingredients above named it may be desirable in some instances at to use about four parts by weight of glycerin and also small percentages of a resinous substance such as rosin oil and a small quantity or a dr ing oil such as linseed oil.

While t e several ingredients above so named are preferably combined in the proportion stated, it will be understood that these proportions may be altered somewhat in the case of each ingredient without destroying the efiectiveness of the mixture.

T e glue is used in order to provide a strong union between the two surfaces which are to be united and although animal glue is preferably used some other adhesive materia such as fish glue, may be substituted in whole or in part for the animal glue. The water serves to dissolve the glue and in preparing the mixture the glue may first be allowed to stand in the water until it is thoroughl softened, after which heat may be applie before adding the other in gradients, or the glue may be given any other suitable preliminary treatment known to the art.

The acetic acid serves to render the glue 5 more soluble, especially when cold, but other acids which afiect glue in a similar Application filed. oh 1?, 1922. Serial Ito.

manner may be substituted in whole or in part without destroying the edectiveness of the mixture. Formic acid is one example of an equivalent acid.

The carbon tetrachlorid is used for its solvent action upon the varnished or parafined coating of the materials to be connected and also for its fire retardant'prop- 'erties. Other substitutes possessing fire retardant properties may be substituted in whole or in part for the carbon tetrachlorid, one such other substance being tetrachloroethane.

The wood alcohol is used for its solvent action, particularly its solvent action on water and benzol, but some other liquid, such as acetone, which possesses similar solvent properties may be substituted in whole or in part for the wood alcohol, without destroying the efiectiveness of the mixture.

The benzol serves as a solvent for varnish, para wax and similar substances, but some other liquids possessing similar solvent propertiesi for example turpentine, may be substitute benzol.

It may be desirable in some instances to use, in addition to the ingredients combined substantially in the proportions above stated, about four parts by weight, of glycerin or some other hygroscopic substance which because of its water absorptive qualities gives a more flexible film without destroying the effectiveness of the mixture. One example of another suitable hygroscopic substance is calcium-chlorid. In many cases the effectiveness of the adhesive mixture is increased by adding a small quantity of rosin oil or other non-brittle resinous substance in order to provide a more flexible film and in some instances also it may be desirable touse about five parts by weight of a drying oil such as linseed 011, in addition to the other ingredients of the mixture, ashcreinbefore described.
